DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly to a door hinge for opening and closing a storage room.

[0002]

2. Description of the Related Art Generally, a refrigerator is configured to supply cold air generated from an evaporator of a refrigeration cycle to a storage room formed therein to maintain the freshness of various foods for a long time.

Recently, large-capacity refrigerators are also favored in homes. In such large-sized refrigerators, a storage room having an open front inside a main body case having an outer body is divided into right and left by partition walls. It is formed as follows. The door is hingedly connected to the front surface of the main body case, and the door is opened and closed by rotating about the clam. This hinge is divided into an upper hinge part and a lower hinge part.
The upper hinge portion bolted to the upper side of the door is pivotally attached to the upper end of the door, and the lower hinge portion is rotatably supported by being pivotally attached to the lower end of the door. I have.

[0004] In particular, as shown in FIG.
Is a hinge plate 3 provided with a downward hinge shaft 3b at its tip.
The hinge plate 3a is fastened to the upper end of the main body case 1 using bolts 3c. And
A door coupling hole 2a is formed at an upper end of the door 2 at a position corresponding to the hinge shaft 3b. Accordingly, the lower end 3 of the door 2 is axially attached to a lower hinge (not shown), and the upper end of the hinge 2 is fastened to the main body case 1 with bolts 3c. The storage chamber (not shown) formed in the main body case 1 is opened and closed by being rotatable about this.

[0005] On the other hand, such a large refrigerator has a too large outer shape, so that it cannot be inserted through an entrance door such as an apartment, the door 2 is removed, and then the main body case 1 and the door 2 are transported separately.
Reassemble this at the installation site.

However, during the process of removing and assembling the door 2, it takes a long time to tighten and remove the bolts 3c. In some cases, if the door 2 is removed frequently, the threads of the bolts 3c will be worn and reused. Becomes impossible. Further, another tool such as a wrench is required to tighten or remove the bolt 3c, so that the refrigerator door 2 cannot be removed and assembled without the tool, so that the work process becomes complicated.

The doors 200 provided with the portions 210 are hinged to the main body case 100, respectively.

The hinge is divided into an upper hinge portion 300 and a lower hinge portion 400 which rotatably support the upper end and the lower end of the door 200 with the main body case 100, and are characteristic of the present invention. The structure of the upper hinge part 300 will be described in detail with reference to FIGS.

An upper hinge 300 is provided with a hinge plate 311 having a hinge shaft 311 so that one end of the upper hinge 300 is attached to the door 200.
10, an auxiliary hinge plate 320 fixed to the main body case 100 so that the hinge plate 310 is detachably connected thereto, and detachable to the auxiliary hinge plate 320 to fix the hinge plate 310 to the auxiliary hinge plate 320. The fixing plate 330 is connected to the fixing plate 330.

First, the auxiliary hinge plate 320 is provided with a pair of rotating support portions 323 at one end on the door side, and a vertical extension portion 322 having an upright standing end at the other end portion and a tip bent outward. And two projections 321 projecting upward from the center. Rotation support part 3
23 is provided with a pair of opposed insertion grooves 324 for inserting one end of the fixing plate 330.

The auxiliary hinge plate 320 is provided in the main body case 1.
The main body case 100 has an installation port 130 formed at a portion corresponding to the rotation support portion 323, the protrusion 321 and the vertical extension portion 322, through which the rotation support portion 323 and the protrusion are formed. The portion 321 and the vertical extension portion 322 are exposed to the outside, and if the urethane 140 as a heat insulating material is exposed inside the main body case 100, the auxiliary hinge plate 320 is firmly attached to the main body case 100 without any additional fixing means. Built-in fixed.

The hinge plate 310 is connected to a hinge hole 31 formed at an upper end of the door 200.
1 is formed at one end, and an auxiliary hinge plate 320 is provided at the center.
A coupling hole 312 is provided at a portion corresponding to the protrusion 321 of the second member. Therefore, the coupling hole 31 is formed in the projection 321 of the auxiliary hinge plate 320 exposed to the outside of the main body case 100.
2, the hinge plate 310 is seated on the upper part of the main body case 100.

On the other hand, the fixed plate 330 has a cylindrical rotating wheel 331 at one end and a rotating pin 33 penetrating therethrough.
The other end is provided with a cylindrical locking portion 334 that is coupled to the vertical extension 322 of the auxiliary hinge plate 320 so that the fixing plate 330 is detachably coupled to the auxiliary hinge plate 320. It is provided in. Cylindrical rotating wheel 331
Has one surface formed of a flat portion 332, and the rotating plate 331 does not contact the hinge plate 310 during assembly and removal, so that the fixed plate 330 can be easily inserted and inserted into the insertion groove 324 provided in the rotation support portion 323. Remove. In addition, when the fixing plate 330 is coupled to the auxiliary hinge plate 320, a semicircular pressing portion 3 is formed at the center of the fixing plate 330 at the lower side.
35 is provided so as to be in contact with the hinge plate 310, and the hinge plate 310 is firmly fixed by pushing the hinge plate 310 toward the main body case 100 side.

Finally, a lid 340 is provided to protect the hinge structure from external impact and to make the exterior of the refrigerator beautiful, and the lid 340 is connected to one end of the hinge 310 on the door side and the fixing plate 330. At one end.

Next, a process of assembling a door using the upper hinge configured as described above will be described. First, the lower end of the door 200 is pivotally mounted on the lower hinge formed at the bottom of the main body case 100, and then the hinge shaft 31 of the upper hinge 300 is pivoted.
1 is inserted into the door coupling hole 220, and the coupling hole 312 is formed in the projection 321 protruding outside the main body case 100.
By fitting the upper hinge part 300 on the upper part of the main body case 100. In this state, the fixing plate 330
After the rotation pin 333 is inserted into the insertion groove 324 and the locking portion 334 is coupled to the vertical extension 322 of the auxiliary hinge plate 320, the fixing plate 330 is fixed and the fixing plate 330 is fixed.
The hinge plate 310 is firmly fixed to the main body case 100 by the pressing portion 335 of FIG. Further, the rotating pin 33
If the flat portion 332 of the rotating wheel 331 faces downward when the 3 is inserted into the insertion groove 324, a gap is created between the hinge plate 310 and the insertion, so that the insertion becomes much easier. Finally, when the lid 340 is fitted to one end of the hinge plate 310 on the door side and one end of the fixed plate 330, the assembling operation of the door 200 is completed.

The door is removed in the reverse order of the assembly. To explain this, first, the fixing plate 3
The lid 340 connected to one end of each of the hinge plate 310 and the hinge plate 310 is removed. Then, the auxiliary hinge plate 32
After the locking portion 334 of the fixing plate 330 fitted to the vertical extension portion 322 of the
When it is removed from 4, the fixing plate 330 is removed. Also at this time, as described above, if the flat portion 332 of the rotating wheel 331 is directed downward, the fixing plate 330 can be easily removed. Next, after removing the hinge plate 310 located on the upper part of the main body case 100, the upper side of the door 200 is pulled up to disengage the lower end of the door 200 from the lower hinge part.
The door 200 and the main body case 100 can be easily removed.

[0020]

As described above, in the refrigerator according to the present invention, the hinge plate for rotatably supporting the door is provided with connecting means without bolts so as to be detachably attached to the main body case, thereby removing and assembling the door. The work can be easily performed without additional tools, and the work time can be shortened.
